people like that (who need to feel love to fill a void and then move on when they are full) are constantly on a rebound! they bounce from one relationship to the next getting their fill of love and then moving on before they can get hurt. i don't think they are interested in sticking it out through the tough. they are only in for the icing on the cake - weather they know it consciously or not that is what happens!
women like us need to stop blaming ourselves for failing to help them!
